Retrieving an exception report from the flash of an AOS product
When an AOS product reboots itself, it will normally save an exception report to the flash which will include vital information for ADTRAN Design Engineers concerning the cause of the reboot. When this happens, it is imperative to alert ADTRAN Technical Support by opening a support ticket, which can be done by emailing firstname.lastname@example.org or by requesting a callback at 1-888-4-Adtran. Evaluating and resolving the cause of a reboot will not only help prevent further reboots of your product, but could also help prevent others from experiencing the same issue.
Prior to contacting Support, an exception report will need to be removed from the flash of the affected unit. There are multiple methods of retrieving the file, but in current AOS, you can not remove the exception report using the web interface.
To retrieve an exception report use one of the following options:
Option A - TFTP
Initiating TFTP transfer...
Received 274839 bytes
If the retrieved bytes shows zero, this likely means the AOS device could notmake a connection to your TFTP server. At this point, proceed back to sub-step “b” or troubleshoot your connection to the server’s IP.
Option B – Xmodem (Console Only)
Option C – FTP
The AOS unit can act as a FTP server. Once enabled, you can use an FTP client to query the unit for a list of its flash and the appropriate exception report file can be retrieved from the unit. The FTP server is not enabled by default so you must follow the steps below (3-A) to enable it via CLI. To enable it via the Web interface, see 3-B.
3-A – CLI Access
ip access-list extended FTP
permit tcp any any eq ftp
ip policy-class <policy name>
allow list FTP self
Note: The last line may need to be above other policy rules if there are other rules that affect FTP traffic.
3-B - Web Interface Access
